There are approximately one pon villages or more that have no trieity, said Dr. Richard Field, ssistant professor of Mechanical [ineering and designer of the re- ■rator. This would be a practical way to vert direct energy into electric- dthout having to bring in diesel ;rators to supply the whole vil- with electricity. †le photovoltaic/thermoelectric [gerator consists of two square ;rs of silicon-coated solar cells, fiber chemical is added to this to |rove electron emission. The sun xes the solar panels causing the to generate electricity. The |er is then stored in an 18-volt lery which is slightly larger than Automobile battery, fhe battery is connedted to a loelectric plate which conducts (current to the cooling fins. The jling fins then cool a 3,600- lic-centimeter area, lis refrigerator is also designed jllapse and become portable, complete structure, including 18-volt battery, weighs approxi- |ely 88 pounds and could be car- over a semi-rough terrain by people. solar-charged batteries can )ly enough energy for 24 hours jut sunlight. re batteries are continuous as as the sun is shining,†Field When there is no sunlight, )h as in India during the isoon, additional batteries can (added. This, however, adds to jweight and cost. There will also ledicine spoilage, but you have cept that.†f ield has sent the photovol- /thermoelectric refrigerator de ls to various government agen- s, including the Solar Energy Re- ih Institute, the United Nations the Energy Department, but project has yet to be funded, le refrigerator will cost about The government is trying to get cell costs down to 1/lOth of W it is now. If that happens, the (of the refrigerator) will reduce around $2,000,†Field said. '“Since the power of the structure self-contained, there is no waste energy in converting the DC (di current) to AC (alternating cur- |t), such as in diesel generators,†designer said. “It is a simple, jle function. †7 ield said since use of photovol- cells is increasing in remote lo gons, they will soon be able to ipete with the diesel powered aerators on an economic scale, le mechanical engineering pro- ar has been interested in solar verfor several years and has writ- books on the subject. He also designed other solar-related [ijects such as a drapery solar liner a portable solar refrigerator for car, which holds a six-pack. ieer ban thal'l 7 regular!] dat ity. ; regular| light, it« their I THE BATT DOES IT DAILY Monday through Friday mei t.
